Physical Modelling of 3D Melts Mixing for Electrometallurgical Aggregates
Abstract
We study the melt mixing in the bath of electro-aggregates and the mixing control system. For this we use physical modelling of electro-vortex flows in conductive, viscous, incompressible liquid. In the article we describe: the task of the modelling; toroidal vortex as a base electro-vortex flow; the interaction of vortexes under two (and more) top electrodes; the mixing in the 3-phases EAF (electrical arc furnace) in comparison to the next generation DC EAF with built-in bottom electrodes; the flow structure in the bath with thin liquid layer and submerged electrodes; some other tasks. In many cases the flow structure can be estimated by approximating the electromagnetic forces field. For some nonlinear, nonstationary effects, like the localization of flow or large-scale 3D auto-oscillations, the physical modelling is the only research method. The results of modelling where confirmed and applied in real technologies.
